Title: Speaker box
Inventor: OGINO YUJI
IPC: H04R1/02
Filed: 1989-04-20
Abstract: PURPOSE:To form a speaker box not deteriorating a transient characteristic and distortion characteristic and not causing wind break noise by forming a bell type sprue shape having the same curvature as air natural flow stream to a port exit and constituting the cross section of a rib controlling the air flow in streamlike shape. CONSTITUTION:A port 3 has an exit of bell type sprue shape having the same curvature as natural streamlike of air 5. Thus, no contract flow is caused in the air 5 flowing the port 3 and suction and delivery of air in an enclosure 2 is implemented excellently and suction and delivery in the enclosure 2 is excellent, and the transient characteristic and the distortion characteristic are not deteriorated because a back pressure load is not increased to a direct radiation speaker 1. Moreover, since the shape resistance is suppressed by adopting the shape of the cross section of the rib 4 controlling air flow to be a streamlike shape, the production of eddy of air due to peeling of the boundary layer on the surface of the rib 4 is eliminated and wind break noise is eliminated.

IPC: H03M1/10
Filed: 1981-06-29
Abstract: PURPOSE:To simply check AC signal transmission, by providing a switch changing over a 2-system signal transmission line into 1-system signal transmission line and a transmission functional check circuit. CONSTITUTION:When changeover switches SW1-SW3 are opened, the 1st system signal transmission line consisting of a transmission filter TRF and a coder  CD and the 2nd system signal transmission line consisting of a decoder DEC  and a reception filter RVF are formed. When a control signal is given to a terminal CTS, the switches SW1-SW3 are closed, the signal transmission lines of the 1st and 2nd systems are changed over to one system to be the test mode.  When a synchronizing signal is given to a test mode terminal SPT, a test use AC signal from a test signal generating circuit TSG is inputted to a functional  check circuit CHK via the DEC, the RVF, the TRF and the CD. Thus, the check of the AC signal transmission can be made simply.

Title: Transmitted illumination type meter
Inventor: MOCHIZUKI CHIHIRO
IPC: G12B11/02
Filed: 1995-04-25
Abstract: PURPOSE: To improve pointedness accuracy and visibility reconcilingly. CONSTITUTION: In this transmitted illumination type meter printed with a slender scale part 25 to be indexed by a pointer on the surface of a dial 9, one side in the longitudinal direction of this scale part 25 is set to be a light transmitted part 41 and the other side to a shading part 43 subjected to a blackening process, respectively. With this constitution, even under such conditions that an illuminating color has been melted in the surface of the dial 9, the shading part 43 alone remains seen as in black, as that the scale part 25 is thus visible, and further, if width (d) of this scale part 25 is set to be slender, the shading part 43 can be surely printed, and thus the extent of pointedness is adjustable in a highly accurate manner.

Title: Arithmetic unit
Inventor: HIROTSU TETSUYA
IPC: G06F7/00
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To speed up operation processing in the case of knowing whether arithmetic operation data including valid data and invalid data is positive or negative. SOLUTION: A data acquisition step 100 acquires effective/ineffective information showing the validity/invalidity of arithmetic operation data, arithmetic operation data used for an arithmetic operation, an arithmetic operation mode showing whether or not an arithmetic operation using a degradation mode is performed and the degradation mode showing whether the arithmetic operation data are only positive numbers or only negative numbers.  A normal mode decision step 101 moves to an arithmetic operation data code decision step 104 when the degradation mode is used, when the arithmetic operation data are only positive numbers, a valid/invalid bit decision step 105 gives when a value is valid, and gives 1 when it is invalid, and when the arithmetic operation data are only negative numbers, a valid/invalid bit decision step 106 gives 1 when a value is valid, and gives 0 when it is invalid. Next, a valid/invalid bit storing step 107 superimposes those values upon the code bit position of the arithmetic operation data.

Abstract: PROBLEM TO BE SOLVED: To improve temperature check accuracy while reducing the thermal imbalance between a condensing means and an infrared sensor as much as possible by inserting and arranging the condensing means and the infrared sensor together inside a probe means in contact with an earhole part. SOLUTION: An arithmetic means 8 is turned into standby state by pressing a power source switch 12, a probe 2 is inserted into the earhole part, and an operating switch 13 is pressed. The arithmetic means 8 drives a chopper 10 and infrared rays radiated from the earhole part are detected by an infrared sensor 4, amplified by a filter amplifier 6, converted to a digital value by an A/D converter 7 and inputted to the arithmetic means 8. At the same time, the temperature of infrared sensor 4 itself is detected by a temperature detector 5, converted to a digital value by the A/D converter 7 and inputted to the arithmetic means 8 as well. As the output of infrared sensor 4, a value proportional to the fourth power difference between the temperature of earhole part and the temperature of infrared sensor 4 itself is outputted.  Since the condensor and the infrared sensor are inserted into the probe, no temperature gap occurs.
